摘要:  摘要:有源配电网的多电源特性有利于释放线路容量、改善电压水平、延缓电网投资。针对含分布式电源的配电网,建立了一种计及电压越限投资成本的有源配电网节点电价计算方法。该方法通过量化分布式电源接入引起的潮流变化对未来容量与电压越限投资的影响,对双向潮流情况下元件投资年限进行求解与修正。在此基础上,利用长期增量成本法计算节点电价,评估了现有网络的容量利用水平与电压越限程度。IEEE 33节点系统算例分析表明,所提定价方法能够反映各节点对有源网络容量与电压越限程度的贡献水平,可以指导合理的电力消费与电网规划。

Abstract:  ABSTRACT:     The characteristic of multi-power supply of active distribution system contributes to relieving unused capacity of network components, improving voltage level and deferring network future investment. With the participating of distributed generation in distribution system, this paper proposes a novel nodal pricing method for active distribution network considering additional reinforcement cost driven by voltage constraint. The proposed approach quantifies the influence of power flow change caused by distribution generation to reflect capacity cost and investment driven by voltage constraint, and then solves and revises the investment years of the components in bidirectional flow. On this basis, nodal price is calculated based on long-run incremental cost method, which reflects network unused capacity and unused voltage in some extent. The results of IEEE 33-nodes system show that proposed nodal pricing method can reflect the contribution level of each node to active network capacity and voltage constraint margin, as well as guide rational power consumption and grid planning.

 

Key words:  active distribution system, nodal pricing, voltage constraint, distributed generation.
